We are trying to move three SGI GL applications to a RH 5.0 Linux system
with Mesa 2.6. Obviously we are facing a problem with the old-fashion
Irix GL problem. It seems that we have two options:
(1) Change the code to be OpenGL compatible.
I have tried to run toogl to convert the code, but there still are many
functions which toogl can't help except just simply deleting them. So I
have to manually change them (e.g., dopup(), getorigin(), getgdesc(),
winset(), getbutton(), getvaluator(), gexit, prefsize(), etc.) . But I
know nothing about this stuff. Where and how should I start to learn the
(2) Find a GL emulator which can run on the top of Mesa. I know there are
repGL, ygl, and vogl which might be helpful. Do you think this is a good
idea to run our GL applications instead of changing the code? Which
emulator would you suggest on Linux?
